Do not trust that this will work!!!
i just set up multiple daily interval waterings per day on multiple zones. I then disabled some ot the zones. Even though the zones were DISABLED the zones STILL WATERED!!!
Best i can tell if you have a set watering interval schudeled, it will override the zone be disabled. To be 100% sure you have to TEMPORARILY DISABLE every set watering time/schedule. If you have multiple set times this is a royal pain.
